FUMIGATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 663,770, dated December11, 1900.

Application led February 20, 1899. Serial No. 706,257. (No model.)

To all whom, it may concern:

Be it known that I, .IOSPHINE MARIE LOUISE MEssnRLI, (born Imbert,) acitizen of the Republic of France, residing at Paris, France, haveinvented certain new and useful Improvements in Fumigating Devices, ofwhich the following is a specication.

My invention has relation to a device for producing gases or vapors forfumigating purposes; and it has for its object to provide a simple andinexpensive device by which gases or vapors adapted for fumigation maybe produced.

In the accompanying drawings I show, in Figure l, a vertical sectionalview of a fumigating-body constructed according to my device. Fig. 2 isa similar view of a device for vaporizing corrosive liquids, the outercombustible covering being removed. Fig. 3 is a similar view of aslightly-modified vaporizer.

In carrying out my invention I may use various substances capable ofevolving gas or vapor under the action of ordinary heat, such ascamphor, menthol, phenol, corrosive .sublimate, or otherreadily-volatilizable substances. l

I iirst take a suitable quantity of the volatilizable substance-say, forinstance, camphor in the form of powdermix with it pulverized wood andclay, plaster-of-paris, or the like, and form the same into a paste bythe addition of a liquid, and while in a paste form I cause the same toassume any suitable shape-as, for instance, a hollow cylinder A. (Seenin Fig. l.) p

When the latter is dry, I cover it with an incombustible varnish andclose its upper aperture with wax D to prevent the gases evolved fromthe outer combustible mass, presently described, from acting upon thecamphor, and also prevent slow evaporation of the camphor. I next take apaste or coating containing any suitable combustible material, as paper,for giving the heat required for vaporizing the camphor and apply thiscoating to the exterior of the cylinder, as shown at P, and the whole isallowed to dry. I then ignite the outer coating around the upper part ofthe cylinder, and the heat produced causes the wax to first melt, whichwill allow the vapors of the camphor to be quickly evolved and toescape, and at the same time the perfume contained in the combustiblecoating also escapes into the atmosphere.

According to my invention all gases not requiring an excess of heat canbe produced and the Vaporizing of salts and of corrosive and otherliquids can be readily effected.

In vaporizing corrosive liquids or to introduce them into a chemicalmixture for the production of gases I use crucibles E, such as leadencrucibles for sulfuric and hydrofluoric acids and the like. 'Ihesecrucibles, which may be of any shape and water-tight, are closed by ascrew-cap C, threaded upon the neck of the crucible, said cap beingprovided with a perforation O', which latter may be covered by awire-gauze D2. The perforation is then hermetically closed by a fusiblesubstance, as wax, as indicated at Di, by the liquid contained in theCrucible. The Crucible may be lined before receiving the liquid with athin coating of perfumed wax and be covered exteriorly, including' thecap, with a similar coating of perfumed wax or varnish. The Crucible isin practice to be inclosed by a combustible coating, such as indicatedat P in Fig. l, excepting the gasoutlet perforation, and the saidcombustible coating is ignited, thus generating heat, which causes thefusible material over the outlet to melt and allowing the evolved gasesto escape.

In order to conduct the evolved gases away from the vaporizer toseparate such gases from those formed by the combustion of thecombustible coating, I screw a tube E upon the threaded neck of thecrucible, as seen in Fig. 3, which tube serves to conduct the gases toany desired point. Where inflam mable vapors are being generated, thedevice would have to be inclosed in aWire-ganze aperture, and a coatingor covering of com sheath. bnstible material for the receiver.r

By my invention I can obtain ataloW cost In testimony. whereof I havehereunto gases or vapors for fumigating or other pnrsigned my name inpresence of two subscrib- I5 5 poses. ing Witnesses.
